"I am keen to trace a silver Vauxhall Insignia which was seen in the area before the incident. We believe the offenders left the area in a car and we have had reports from witnesses about a car wheel-spinning away a short time after the burglary.

"I am keen to speak to anyone who has any information about the Insignia car and who may have been using it."

If you have any information you can call Reading CID on 08458 505 505 or the charity Crimestoppers on 0800 555 111.
